Given a set of ordered quantities, a list of the fractions of values at or below each quantity is know as a plotting position. A quantile-quantile plot compares observed quantiles with quantiles for a sample of the same size from a similar distribution, determined by evaluating the quantile function for the similar distribution at the plotting positions.
